I went when I was around 22 weeks. I was alright, tried to stay away from the smoking section. Only had problems when my mom decided we needed to stay for 7hrs instead of 2, haha.
Lol I go once in a while. My mom is a gambles alot. I try going to the non smoking area but it seems like there no goo machines in that area lol.
Make sure you step out for fresh air every now and then they say second hand smoke is worse than first maaamas
